Louvers

Louvers for Steel Buildings
Although best used to generate cross flow for larger devices, louvers often provide the only ventilation in smaller buildings. Heritage offers fixed 3'x3', 3'x4', and 4'x4' or adjustable 3'x5 'and 4'x4' GalvalumeĀ® louvers in Polar White or mill finish, each with bird screen, 18-gauge frame, and 20-gauge fins.
